Data & Analysis skills
Data skills read a table, a query or a set of figures that you paste and say what is in it: a plain-language description of a table, a check of a SQL statement, a caption for a chart. They cannot connect to your database or recompute from files, so every number they mention must come from what you pasted. What is not here: forecasting, statistical claims from tiny samples and anything that needs a live data source. We test by comparing each stated figure with the input and by planting traps such as a misleading total, and we report which model fell for them.
